A percentile is the value below which a given percentage of the data falls — the 90th percentile is the point beneath which 90% of the values lie. Percentiles turn a raw number into a rank you can interpret: a test score at the 90th percentile beat 90% of the other scores.
This calculator uses the linear-interpolation method, the same as the spreadsheet PERCENTILE.INC function. It sorts the data, computes a rank of (p ÷ 100) × (n − 1), and if that rank falls between two positions it interpolates linearly between the neighbouring values. It also returns the full five-number summary (minimum, first quartile, median, third quartile and maximum) and the interquartile range.
Worked example: for 5, 7, 8, 12, 14, 18, 21, 25, 30, 35 (ten values) the 90th percentile has rank 0.90 × 9 = 8.1, which lies between the values at positions 8 and 9 (30 and 35); interpolating 0.1 of the way gives 30 + 0.1 × 5 = 30.5. A table below gives the percentile rank of every value, which is handy for growth charts, exam scoring and benchmarking.

Maitiro ekufungidzira percentile?
Data iri kunyorwa uye a rank of (p/100) · (n - 1) inofungidzirwa. Kana iyo rank iri nhamba yakazara, mhedzisiro iri panzvimbo iyi inodzokera; kana kwete, iyo kalkulator inowedzera pakati pezviviri zvinosangana. Iyi ndiyo nzira yekuti PERCENTILE.INC iite basa iri.
Chii chinonzi chiyero pakati pepercentile nequartile?
Kwartiles ndezvimwe zvidimbu zvemasenti ayo anoparadza data kuita zvidimbu zviviri zvakaenzana: chidimbu chekutanga chinonzi 25th percentile, chinotevera chinonzi 50th percentile (median) uye chechitatu chinonzi 75th percentile.
Chii chinonzi interquartile range?
The interquartile range (IQR) ndiyo yechitatu quartile minus the first — the span of the middle 50% of the data. Because it ignores the top and bottom quarters it is a robust measure of spread and is often used to flag outliers.
Chii chinonzi 90th percentile?
Izvi zvinoreva kuti 90% yedata iri pasi pechiyero ichi, saka 10% chete yezvinoratidza kuti zvichave zviri pasi pechiyero ichi. Kuwana zvibodzwa pa90th percentile kunoratidza kuti waita zvakanaka kupfuura 90% yevamwe vadzidzi.
Chii chinonzi 50th percentile uye nei ichisiyana nemedian?
Ndinoda. The 50th percentile inoparadza data kuitira kuti hafu yezvikwereti zvirege kudonha pasi pake, izvo zvakanyatsojeka pfungwa yemucheto.
Nei imwe nzira ichigona kupa imwe percentile yakasiyana?
Kune akawanda akasimbiswa mapercentile mashoko. Iyi kalkulator inoshandisa kusanganisira linear interpolation (PERCENTILE. INC); the exclusive nzira (PERCENTILE. EXC) uye the nearest- rank nzira kuisa the percentile zvishoma zvakasiyana, saka zviito zvinogona kuchinja zvishoma pakati pezvinhu, kunyanya padiki data sets.
